Mapping inlet boundary

calf.Z · November 29, 2018, 21:11

Hello formers,

I am wondering how I can map the velocity from one surface into inlet, because I am researching DNS and I need this inlet boundary to generate the turbulence structure within a short pipe length.

By searching the Forum, I have found mapped and timeVaryingMappedFixedValue may be suitable for my problem. Do you
have some experiences in this two boundaries?

Any hints or advice is highly appreciated.

Thank you,
Calf.Z

Anyone is experienced with these two boundaries？or do you have some recommendations about the inlet boundary when using DNS?

Thank you very much!
